which the following isa specification, reference being had to the accompanying draw-v ings.

ria-ls, and the object is to provide a shingle strip and method of making the same which consists in severing a strip ofv flexible-material longitudinally along adeviating or zigzair path to form two shingle' strips having in ented edgesforming point-downshingle` ends, and forming each shingle end with an enlargement which is subsequent-ly bent under to form a locking tab,

' which my improved shingle strip is manu-Y Thesev and other objects are accomplished by what I now regard, from among other possible forms and arrangements, as the preferred embodiment of my invention, to be hereinafter described, .illustrated in the accompanying drawings and particularly pointed out by the ,appended claims.

In the drawings, Figure I is a View inplan of a strip of roofing' material illustratingthe manner lin which it is` severed lon itudinally to form two shingle strips.

igure II is a View in planA of a portion of a shin le. strip with formed shingle ends and showi the latter folded under to constitute looking tabs., v

Figure III is a view in top-plan of a num-` ber of shin le strips, constructed in accordance wit my invention, and illustrating the manner in which superposed strips are interlocked while simulating" pointdown shin lesg' and,

method by Considering first he preferred factured reference is `had to'Figures I and II wherein 10 indicates a strip of web roofing material such as bitumen impregnated` felt, paper, or other fibrous materiahnsually surface coated with granular or silicious material such as slate,l silicafor the like, te form a hard wear and weather resistant surface. l

The strip 10 is severed ,l'ongitidinelly,"v and this may be accomplished -continuously as the web material isy This invention -relates'vto roofing mate-v lockin members 18 enga elvered from a roll. V` of sai strips to enhance the lockingeifect.

and fed through a suitably constructed machine for this purpose.

.The web is 'severedalon a deviating or zlgzag path, centrally, to orm twoy shingle strips 11 and 12, as a result of-.which the severed edges of the strips are formed with point-down shingle ends 13 having converg# ing side edges terminating in shingle points, u

so that when the,v strips are overlayed in applylng the strips to a roof the effect is vthat o f diagonally laid shingles.

Each shingle end 13 is formed, during the process of splitting the web, with a tip enlargement 14, preferably ofthe configura-- tion shown, comprising a straight edge 15 and tapering side edges 16 which extend 1n the general direction of the'v side edges of thev shingle ends but at a slightly different angle. The lines of incision, when forming the side edges of the shingle ends, are continued into the tri enlargements 14, as indicatedat 17, to de ne auxiliary lock- -ing members 18 which are thus partl severed from said enlargements 14.l It

be noted that in forming the tipv enlarge-v ments 14 complementary e i are formed between acent shingle ends shaped .recesses 19 13 of each strip 11er 12,V the formation-'of vthe auxiliary locking members 13 resulting in the provisionxof opposed shoulders 2O in the recesses 19.

The shingle strips 11, 12 are iinishedby V:folding under the tip enlargements 14 along a line connecting the ends of theincisionsf:

olding being indicated by 17, the line of lvals clotting in Figure II. The folding ofthev tip enlargements 14 maybe accomplished pose; and .if desired the folding mechanism 4by special machinery designed .for the pun a win be noted than@ auxiliary locking' members 18 will remain unfolded and A'will' u project'bey'ond the edges of the shingle ends 13.

improved shinglestrx s i' i ing tabs thus securely 4ill b h edges ofthe underlying strips an t e auxiliary ging the underside yThe shoulders function to prevent accidental separation of two adjacent strips j if the shingle ends 13 are raised or shifted l' es relatively. Fastening members such as nails are driven through the shingle strip into the roof preferably at points directly above the locking notches 19, the exact allocation of the nails being such that the tip enlargements of a succeeding strip mayy be readily engaged in the notches.K If desired additional nails may fbe employed in other portions of the strip providing that they be overlapped by the succeeding strip to precludethe possibility of water entering between thef superposed layers.

.While the roofing material ofmy invention' lends itself readily to being formed into l roll packages for shipment, it may obviously be cut to convenient lengths. (say eight, ten or twelve feet, which may be easily handled in laying) and stacked for'flat packaging, g

suitable stiiening sheets of corrugated cardboard or its equivalent'being incorporated in the package 'to protect the shingling .againstfflexure ordamage in the course of itstransportation. Y

, ,Having 'thus described 'my invention, I claim: l

1. A shingle strip of flexible water-proof material havingone longitudinal edge formed with alternating angular projections simulating point-down' shingle ends andvrecesses of corresponding size and configuration, each of said angular projectlons having an integraly ,tip `enlargement lwith converging incisions defining opposed lateral 'projectionaand said tip enlargements beingadapted to be'folded under to consti-l tute 'it/lookin tab. Lf f 2'. A shing e strip of flexible water-proof material/one longitudinal, edge whereof is severed to define alternating projections simulating point-down shingleends and recesses of right angled configuration' and corresponding size, each of said projections -having an integral tip enlargement with 'converging incisions defining opposed lati. material havingy a longitudinal edge `seve ered to'provide angular projections'slmulateral projections, and Ysaid tip enlargement beingcapable offolding upon' itself to constitute a locking tab.

3. A shingle stripof flexible water-proof ing point-down-shmgle ends and recesses of corresponding size and configuration, each ofv said projections having an integral enyerally beyond the shingle largement with opposed lateral projections partlyv severed whereby said enlargement may be folded under to form a locking tab leaving the projections divergingly unolded to constitute auxiliary locking men1- ers. 4. A shingle strip of flexible water-proof material having one ledge deviatingly severed to simulate point-down shingle ends with mutually configured alternating recesses, eachsaid shingle point having an in.

tegral enlargement with `converging incisions and being adapted for retroversion to constitute a locking tab, said incisions delining locking ears that divergingly project latpoint edges when said p oint is underfolded. f

5. A shingle strip of flexible water-proof material one longitudinal edge whereof is severed to form substantially right angled point-down shingle points with mutually configured equalsized alternating recesses,

v each said shingle point having an integral enlargement With converging incisions and being adapted for underfolding tol constitute a locking tab, said incisions defining diverging members projecting laterally beyond the shingle pointoblique edges.

I6. As an articleof manufacture, a strip of flexible waterproof "material having one edge deviatingly severed to simulate point.- down shingle ends with mutually configured recesses between each pair of yadjacent shingle ends, and an integral enlargement with converging incisions at the tip of each shingle end, said shingle ends when folded under constituting locking tabs adapted to enter the recesses of anunderlying corresponding strip of said material.

7. A y.Water-proof covering comprisingl a WILLIAM FR-EEGARD.
